The outer peripheral surface of each shoe 35 carries a suitablelining 36. The shoes are recessed to receive three studs 37 fixed to an end face of rotor 33. Each shoe is also provided with an arcuate groove and these three grooves together afforda continuous circular groove in which an endless circular coil spring 38 is received. Spring 38 draws the shoes 35 inwardly until they abut each other and studs 37. It will be clear that until the rotor 33 acquires considerable speed, in this case about 1000 R. P. M., it will not become coupled toshaft 25.

The hand operated driving means for pump 10 include a' bevel gear 39 (Fig. 4),- fixed to the rotor shaft 25, and a mating bevel gear 40 which is fixed to the inner end of a short horizontal shaft 41. On the outer end of shaft 41 is fixed a pinion 42. Between the gear 40 and pinion 42 a sleeve 43 is mounted on the shaft and is held against relative longitudinal movement thereon by the gears. The shaft 41can turn freely in the sleeve. This sleeve 43 is mounted in a hub of the-bracket 32, above described, fora limiteddegree ofaxial sliding movement. A pin 44 in said hub rides in keyway 45 in sleeve 43 and holds the latter from turning. The sleeve 43 has twolongitudinally spaced recesses 46 in either of which a spring pressed ball 47, mounted for radial sliding movement in said hub, may engage. When ball'47 is engaged in thetright' hand recess 46, shaft 41 will be in the proper longitudinal position for bevel gear 40 to' mesh with its mating gear 39. The pinion 42 is formed with a-knob 48 by means of which it may be grasped and pulled outwardly until gear 40 is disengaged from gear 38.-The hinged-door 23 allows access to knob 48. The engagement of "ball 47 in the left hand recess 46 defines the position of shaft 41 in which the gears are disengaged and the ball yieldingly holds the shaft in such position.

The pinion 42'is driven by a spur gear 49 (Fig.2). Fixed to gear 49 is a pinion 50 (see also Fig. 5). These connected elements 49 and 50 are mounted to turn on a stud 51, fixed toframe 32. The pinion 50 is driven by a gear 52, mounted to turn on a stud 53.

fixed in frame 32. Stud 53 has a hole 54 therein to receive the shaft of a crank handle 55 (indicated in dotted lines in Fig. 3) and the outer end face of the hub of gear 52 is formed with shoulders 56 to receive the projecting ends of a pin 57, fixed to and passing diametrically through. crank55. Adjacent the shoulders 56 are cam surfaces 58. The

arrangement is substantially the same as that provided for cranking automobile engines by :hand. The hand crank 55 may be put in in door 23 (Fig. 3) or the door may be opened for the purpose if desired.

- For normal operation, the crank 55 will be withdrawn and the bevel gear 40 will be moved out of mesh with gear 39, whereby the motor 24 will be free to drive pump 10 without turning the gear train which constitutes the transmission between the hand operated element (the gear 52) and shaft 25. The power operation of pump 10 is the usual one, except that the motor 24 starts up under no appreciable load, due to the centrifugally operated clutch comprising the elements 35 and 36, which at starting and at low speeds leave the rotor 33 free to turn on its shaft 25. After the rotor 33 acquires considerable speed, say about 1000 R. P. M., the elements 35 will be forced into engagement with element 36 to'couple the rotor to its shaft. The pump, it will'be clear, is intend-ed'to rotate at high speed. Consequently, for satisfactory hand operation, it is necessary to provide the transmission gearing which will multiply considerably the speeds which may be effected by hand cranking. Necessarily, this'kind of gearing requires more efiort on the part of the operator and because of this fact, it becomes important to reduce the load to a minimum. The removal of the load of the relatively heavy rotor 33 is an important factor and this is accomplished by the centrifugally operated clutch which responds to rotor speed and, when the motor :is not energized, frees therotor from its shaft. For the hand operation, the operator first pushes in on the bandle48 throwing gear 40 into mesh with gear 39, and then puts crank 55 in place as indicated in Fig. 3, after which he is enabled by turning the crank to rotate the pump at a sufiiciently high speed to secure satisfactory operation.

The invention has been disclosed herein, in an embodiment at present preferred, for illustrative purposes but the scope of the invention is defined by the appended claims rather than by the foregoing description.

What I claim is:

In a liquid dispensing apparatus, a pump-and adriving motor therefor; a frame including opposed members disposed in spaced relation, one supporting the pump and the other the motor, and spaced connecting side members; said motor and pump havingtheir respective drive shafts extending toward each other in the space between said several members, a coupling for connecting and transmission gearingcarried by said bracket for driving one of said shafts, said gearing including a manually disengageable element to interrupt thetransmission to said shaft.
